I’m not sure what you mean by your example. But to elaborate, there was a discussion a few years ago on the Livepatch client repo here about whether it was possible to build the Livepatch Client Snap on different bases to improve the boot time of cloud instances running Ubuntu Pro. In the ideal case the cloud image would install the Livepatch Snap using a base that was already pre-seeded in the image, in the worst case it would download a non-seeded base and increase the boot time.
To alleviate this problem the Snap can simply be built on the bare base (the build-base would still be the latest base i.e. core22 to get the latest snapcraft features). Now installation of the Snap will always be speedy because the bare base is a very minimal set of files and we don’t need to keep the overhead of maintaining multiple bases.
To add an extra caveat on the above, although the work was done to build the Snap on all the bases, it seems the Ubuntu Pro client defaults to installing from
latest/stable making the benefit of multiple bases moot. But in any case, moving to the bare base has tangible benefits.
Hope that makes sense.
